Echo Sub must be paired with a compatible Echo device. In order to get optimal left/right sound, you must pair Echo Sub with two Echo (2nd Gen) or two Echo Plus (2nd Gen) devices. Currently, Echo Sub only supports music playback over your wireless network, and does not support Bluetooth, 3.5 mm AUX in, or TV/video. Some Echo devices support different stereo and subwoofer configurations. Learn more.
How to set up speakers for Stereo sound
For stereo sound, pair two supported Echo devices of the same model to create a speaker set. One Echo device plays sound on the right channel (right side), while the other plays sound on the left channel (left side). For richer bass, you can pair Echo Sub to supported Echo devices.
Note: Paired Echo speakers only support music content. Line-out and Bluetooth connections to external speakers aren't recommended.
To get started, download the latest version of the Alexa app and check that your Echo devices also have the latest software update. For more information, go to Alexa Device Software Updates.
To create a speaker set:
Place your devices in the same room, several ft (1 m) apart from each other.
Note: If you’re using Echo Sub, place it on the floor in the same room as the other speakers.
In the Alexa app, select the Devices icon, and then the icon.
Select Add Stereo Pair / Subwoofer.
Select Speaker Sets, and then follow the on-screen instructions.
